Which of the following statements regarding Type I diabetes mellitus is true?
Patients usually have normal insulin levels and significant insulin resistance in peripheral tissues.
Patients often are treated with diet alone.
Patients frequently are obese.

Which of the following will increase ionized serum calcium?
Elevated serum albumin
Alkalosis
Acute hypomagnesemia
Hypoparathyroidism
Acute hyperphosphatemia
Which of the following statements regarding pheochromocytoma is true?
It is a common adrenal cortical malignancy.
Pheochromocytoma rumors are not directly innervated, and catecholamine release is random.
It is a common cause of primary hypertension.
Cardiovascular effects from pheochromocytoma are treated easily with deep anesthesia.
It is diagnosed easily and reliably by measurement of free catecholamines in the urine.
Which statement regarding Cushing’s syndrome is false?
Most cases occur secondary to bilateral adrenal hyperplasia.
Cushing’s syndrome usually represents adrenal adenocarcinoma when it occurs in older patients.
Twenty-five percent of cases are caused by adrenal neoplasm.
It may occur iatrogenically from steroid treatment of chronic illness.
It may be caused by an underproduction of cortisol by the adrenal cortex.
True of hypoglycemia in the patient undergoing general anesthesia, except:
Is diagnosed easily by recognition of the usual signs and symptoms
Causes effects that are misinterpreted as light anesthesia
Often occurs inadvertently in diabetic patients who receive insulin perioperatively
Occurs more commonly in diabetic patients with renal insufficiency
Reflex catecholamine release causes tachycardia, hypertension and diaphoresis
Which of the following statements with respect to patients with Addison’s disease is false?
The predominant cause of Addison’s disease is autoimmune destruction of the adrenal gland
Patients with secondary forms of Addison’s disease are always hyperpigmented
Treatment includes replacement of mineralocorticoids
Diagnosis is confirmed by failure of adrenal gland to respond to exogenously administered ACTH.
Treatment involves replacement of glucocorticoids
Which of the following statements regarding the posterior pituitary are true, except:
It is composed of terminal nerve endings that extend from the ventral hypothalamus
It secretes vasopressin
It secretes antidiuretic hormone (ADH)
It secretes oxytocin
Acromegaly as consequence of excess growth hormone excreted in this region
Which of the following statements regarding diabetes insipidus is true, except:
It can occur following intracranial trauma
Urine output is highly concentrated
Symptoms include polydipsia
There is inadequate secretion of ADH
Can be caused by destruction of the pituitary gland by lesions or surgery
Patients with mild to moderate hypothyroidism
Are at significant risk for perioperative congestive heart failure
Are at significant risk for postoperative ventilatory support
Can be anesthetized safely without preoperative thyroid supplementation
Are very sensitive to the effects of anesthetic drugs
Should have urgent thyroid replacement before surgery if there is history of coronary artery disease
